<h1 class="topictitle1">After the System Disk of a FusionOne Compute VM Is Restored to a New VM, the Target VM Fails to Be Started</h1>
<div><div class="section"><h4 class="sectiontitle">Symptom</h4><p>After the system disk of a FusionOne Compute VM is restored to a new VM, the target VM, upon startup, enters the <strong>Boot Manager</strong> page and cannot be started using any boot option.</p>
</div>
<div class="section"><h4 class="sectiontitle">Possible Cause</h4><p>When the system disk of a VM is restored to a new VM that runs a different OS or OS version, the boot option of the source FusionOne Compute VM is BIOS, but that of the target VM can only be UEFI.</p>
